TRANSOM ,FASTENER AND PIVOT.

SPECIFICATION forming part of teaersraa No. eospee, dated August 2, 1898.

' Application filed August 26,1897. $erialNo. 649,591. Ell o model.)

To all whom, it may concern:

Be it known that we, CHARLES M. BRIGHT and WILLIAM O. BALLARD, citizens of the United States, residing at Fancy Farm, in the county of Graves and State of Kentucky, have invented certain new and useful Improve-' ments in Transom Fasteners and Pivots; and we do hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

bination, with said ratchet, pawl, and means for freeing the same, of a stop which automatically prevents the said sashand ratchet from being turned to open the former too far.

The said invention more specifically consists in the construction and combination of particularly set forth.

parts hereinafter more and claimed. r

In the accompanying drawings, Figure 1 represents'a perspective view'of a pivoted sash or vertical transom, its frame, and the pawl and ratchet devices embodying my invention; Fig. 2 represents a side elevation of the said pawl and ratchet and their casing detached from the frame. Fig.- 3 represents a View similar to Fig. 2 of a modified form of the said devices, and Fig. 4 represents a detail View of the spring-pressed pin and proximate parts.

A designates the fixed window-frame; B, the sash-frame, pivoted therein by gudgeons C; D, the spring-pressed pin working through frameB into a recess 1) of frame A; E, a spring connecting the said frames and serving to replace the said sash-frame'in its closed position, and F the cord which withdraws the said pin from engagement. The above-men- One of the side walls of frame A is cut .through near its middle, forming an opening or recess G. Into this is fitted a casing H, approximately of tray form, open on the outer side and having a hole for one of the gudgeons O, which turns freely in a bearing-plate I, of skeleton form, fastened to the said casing. A cam and ratchet-collar J, fastened on the said gudgeon between the said plate and casing, is provided on one side with a series of teeth j, on the other side with a single tooth 7t, and below the said series with a cam Z.

An escapement p'awl K, pivoted on a pintle K, is arranged to engage one or another of the teeth j, according to position, by means swell or enlargement 10 that is arranged to be struck by the said cam for automatically disengaging the said pallet from the tooth. The other pallet 70 of' the said escapementpawl is arranged to engage the tooth 7c aforesaid'to act as a stop in preventing the frame B and teeth j from turning too far in the direction away from the pallet 70 The pallet k is in position to be struck by the cam aforesaid for turning the pallet lo into position to The spring aforesaid 8o engage the teeth j. engages the lower point ofthe heart-shaped escapement-pawl K, so as to hold one pallet or the other in engagement, according to the position of the said pawl.

Theoperation is as follows: When the sashframe B is to be tilted to let in the air, the spring catch or pin D is withdrawn from engagement by pulling on cord F, and the said sash'is tilted backward until the pallet 70 engages one or another of the teeth j, accord- 9o gagement, at the same time shifting the po- 5 sition of the pawl as a whole until the pallet 70 is in its position of engagement and the spring M is holding it there. The sash is then released, and the action of its spring E 50 tioned parts are old and well known. throws it to, causing the cam Z to strike the mo pallet 7.; and restore the pallet k to its position of engagement with the teeth j. The pallet thus serves in a double function, being by its engagement with tooth 7a a stop to prevent the sash from being opened too far and assisting the cam to shift the pawl back into its first position.

As shown in Fig. 3, the spring M may be dispensed with and an upwardly-extemling weight N, attached rigidly to the eseapementpawl, used instead.

A lid 0, pivoted to the frame A, may be turned at will to cover the recess G and the parts therein. This of course will be its general position. Although the sash B has been shown upright, the devices above described, when employing the spring M, may be used with the ordinary horizontal pivoted transom.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is"

1. In combination with a pivoted sash and a collar carrying a series of ratchet-teeth j on one side and a tooth 7.; on the other, an escapement pawl provided with pallets arranged to engage respectively the said teeth and 7.: and a spring arranged to hold either one of the said pallets in engagement according to position substantially as set forth.

2. In combination with a pivoted sash, a collar turning with the gudgeon thereof and provided with a series of ratchet-teeth on the other side and a cam below the said series, and an escapement-pawl provided with two pallets and held in alternate engagement with the said tooth and series of teeth, the pallets being arranged and constructed with respect to the said cam so as to be shifted from one position to the other and back again by the action of the said cam on them successively and the movement of the sash substantially as set forth.

3. In combination with a pivoted sash and means for closing it automatically, a series of ratchet-teeth turning with the said sash, an escapement provided with a pairof; pawls one of which engages the said teeth, a cam arranged to strike the said pallet for freeing it from the said teeth as well as to similarly act on the other pallet in reverse motion, and a device turning with the said sash and engaged by the latter pallet the same cam freeing it substantially as set forth.

4:. The combination with a pivoted sash,and a ratchet carried thereby, of a double-armed pallet arranged to engage in the ratchet in one position of the pallet, and a cam movable with the ratchet and playing between the arms of the pallet to strike either arm thereof, whereby the cam is adapted to free the pallet from the ratchet when the sash is opened to substantially its full limit and to restore the pallet to its initial position as the sash is closed, substantially as described.

The combination with a pivoted sash, of a ratchet-formed cam movable with said sash, a constantly-active pawl engaging with said cam to hold the latter and the sash in either of several positions and coacting with said cam to limit the movement of the sash in one direction, and means operated on a reverse movement of said sash to return the pawl to its normal position in. locking engagement with said sash, substantially as described.

6. The combination with a pivoted sash, of a ratchet-formed cam movable with said sash and having a stop-lug, a double-armed constantly-aetive pawl having one arm thereof normally engaged with the cam to hold the latter and sash in different positions and adapted to have its other arm thrown into the path of the stop-lug on said cam to arrest the continued turning movement of the sash in one direction, said cam being adapted when turned in a reverse direction to act on the last-named arm of the pawl and restore the latter to its normal position, substantially as described.

7. The combination with a sash, of a collar provided with a cam between ratchet-teeth and a stop-lug, and a constantly-aetive pawl arranged to be acted on by said cam during the back-and-fortjh movements of the collar and sash, substantially as described.

In testimony whereof we ai'lix our signatures in presence of two witnesses.
